> Oh well,The depth of the plank cut into the frame increases with the ratio of
1/cosine(angle)
so, 1 / cosine(15 degrees) = 1.03527618 = 3.5% increased thickness
You can plug it into Google to figure out

Frame bevels are relatively easy, it was the reduction of the frame for
plank thickness that I was curious about, starts to make a lot of
difference with plank thicknesses of 1/2 in or more.
Oh well, out with the Goudgeon Bros book next time I take up a big
project. Excellent section on lofting. They have a new update out by
the way.

made the frames square, and took the belt sander with a 36 grit belt
to the frames and beveled them to 'eye', working up, one strake at a
time. In the end, boat building isn't rocket science.
When the plank is at an angle the amount would be greater than plank
thickness. Been a while since I have read up on lofting, how do you do
this?

Are these bulkheads less the hull thickness?
By the way thanks for your pioneering efforts on this Bruce, when I
eventually get around to playing with freeship I already will have had a
tutorial courtesy of your commentary here.

> Bruce in NJYes, Free!Ship can make accurate bulkheads, [using the
Point!InsertPlane command]. It is a bit clunky, but I just did a test
of it, and did get a developed bulkhead. Hint, the edges of the
bulkheads must be made 'crease edges'. Hopefully, with practice, I
can get over the learning curve trouble with this.

I think it can now, and also I recall reading that the 'frames'
feature is slated for the next version release of the program.
Just cutting out the strakes, printed with a laser printer on
cardboard allows you to make a 3D model. I have a Shivaree model
right now.

Attached is a study of one Phil Bolger's favorite designs, Shivaree.
An outboard runabout, 18 ft x 7 ft, rough water capable, and one of
the few Bolger designs that he has chosen to personally own.
